</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
The <STRONG>menu</STRONG> library provides terminal-independent facilities for composing
menu systems on character-cell terminals. The library includes: item
routines, which create and modify menu items; and menu routines, which
group items into menus, display menus on the screen, and handle inter-
action with the user.
The <STRONG>menu</STRONG> library uses the <STRONG>curses</STRONG> libraries, and a curses initialization
routine such as <STRONG>initscr</STRONG> must be called before using any of these func-
tions. To use the <STRONG>menu</STRONG> library, link with the options <STRONG>-lmenu</STRONG> <STRONG>-lcurses</STRONG>.
</PRE><H3><a name="h3-Current-Default-Values-for-Item-Attributes">Current Default Values for Item Attributes</a></H3><PRE>
The <STRONG>menu</STRONG> library maintains a default value for item attributes. You
can get or set this default by calling the appropriate <STRONG>get_</STRONG> or <STRONG>set_</STRONG>
routine with a <STRONG>NULL</STRONG> item pointer. Changing this default with a <STRONG>set_</STRONG>
function affects future item creations, but does not change the render-
ing of items already created.

Routines that return pointers return <STRONG>NULL</STRONG> on error. Routines that
return an integer return one of the following error codes:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argument.
<STRONG>E_BAD_STATE</STRONG>
Routine was called from an initialization or termination function.
<STRONG>E_NO_MATCH</STRONG>
Character failed to match.
<STRONG>E_NO_ROOM</STRONG>
Menu is too large for its window.
<STRONG>E_NOT_CONNECTED</STRONG>
No items are connected to the menu.
<STRONG>E_NOT_POSTED</STRONG>
The menu has not been posted.
<STRONG>E_NOT_SELECTABLE</STRONG>
The designated item cannot be selected.
<STRONG>E_POSTED</STRONG>
The menu is already posted.
<STRONG>E_REQUEST_DENIED</STRONG>
The menu driver could not process the request.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno(3)</STRONG>).
<STRONG>E_UNKNOWN_COMMAND</STRONG>
The menu driver code saw an unknown request code.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
The header file <STRONG><menu.h></STRONG> automatically includes the header files
<STRONG><curses.h></STRONG> and <STRONG><eti.h></STRONG>.
In your library list, libmenu.a should be before libncurses.a; that is,
you should say "-lmenu -lncurses", not the other way around (which
would give a link-error when using static libraries).
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These routines emulate the System V menu library. They were not sup-
ported on Version 7 or BSD versions.
The menu facility was documented in SVr4.2 in <EM>Character</EM> <EM>User</EM> <EM>Interface</EM>
<EM>Programming</EM> <EM>(UNIX</EM> <EM>SVR4.2)</EM>.
It is not part of X/Open Curses.
Aside from ncurses, there are few implementations:
<STRONG>o</STRONG> systems based on SVr4 source code, e.g., Solaris.
<STRONG>o</STRONG> NetBSD curses.
